Open Source Database
PostgreSQL is an open source object-relational database system which originally evolved from the Ingres database project at the University of California, Berkely. PostgreSQL has a comprehensive set of features which make it well suited to data warehousing and reporting.
We've supported some web applications using PostgreSQL, but have found that MySQL is the most commonly deployed database.
